Patent GB-328435-A (GB)
Title: Improved means for creating a continuously rotating member at predetermined stopping points
IPC: B41B17/06
Filed: 1929-04-23
Abstract: 328,435. Uher, E., and Uhertype Akt.- Ges. April 23, 1929. Applied by driving-mechanism disengagers; periodic. - In apparatus for arresting a continuously-rotating clutch-driven member at selected stopping points, the driven member carries a brush adapted to wipe a series of contacts until it reaches a contact the circuit of which has been closed at a keyboard, electromagnets then being energized to (1) disengage the clutch (2) apply a brake to the driven member and (3) effect a fine adjustment. The application of the invention to a photographic type-composing machine as in Specification 331,305, [Class 98 (i), Photographic cameras &c.], is described. The electric motor 10 drives continuously a disc 12 slidably keyed to the sleeve- 13, the end 14 of which frictionally engages and drives the disc 15. The latter is fixed to a casing 9 carrying a mirror 8 adapted to reflect the selected character from the axially adjustable matrix drum 4 to the sensitive surface 3. Means for arresting the rotation of the casing 9 comprises a brush 22 on the disc 15 adapted to wipe a series of fixed contacts 23 of which a selected member, e.g. 23a may be brought into circuit by depressing the corresponding key on the key-board 26. When the brush 22 reaches the contact 23a a circuit is closed through the battery 24, electromagnet 20, electromagnets 32, and the metal of the machine to the brush 22. The electromagnet 20 firstly raises the spring-loaded sleeve 13 disengaging the clutch 14, 15, and secondly arrests the disc 15 by lowering the friction disc 18 against the tension of the leaf spring 21. Immediately thereafter the electromagnets 32 effect a fine adjustment by lowering the spring-loaded sleeve 30 so that the claw couplings 28, 29 engage. The contacts 23 are arranged in two concentric rings, Fig. 3, which are adjustable about their centre point by means of the screws 43 and slots 44.

IPC: G21K1/04
Filed: 1958-04-23
Abstract: 867,240. X-ray apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 8, 1959 [April 23, 1958], No. 12907/58. Class 98(1) Apparatus for defining and varying the crosssection of a beam of penetrating radiation comprises a first pair of blocks, between which the beam passes, movable transversely across the beam, and a second and third pair of blocks located respectively before and after the first pair with respect to the direction of travel of the beam, the second and third pairs being movable transversely across the beam in a, direction different to that of the first pair; the thickness of the first pair of blocks measured along the length of the beam is substantially equal to the combined thickness of the other two pairs. The beam of radiation 23 passes as shown between the pair of blocks 5 and 6, 71 and 81, 7<SP>11</SP> and 8<SP>11</SP> of radiation-absorbing material (Fig. 1). The blocks 5, 6 are transversely adjustable towards or away from the beam, and the other two pairs are similarly adjustable but in a direction at right angles to that of blocks 5, 6. (Blocks 71, 711 and 81, 811 are joined by rods 9, 10 so that the outer pairs of blocks move together). The blocks thus define between them a beam of rectangular section which can be varied in size. The source 1 of X or y radiation is enclosed in a mass of radiation-absorbent material 2 having a conical aperture 4. Blocks 5 and 6 are constrained to move in circular arcs centred at 1 by means of attached rollers 11 and 12 engaging in arcuate grooves 13, 14 in members 15, 16 forming part of a supporting framework 24. The other pairs of blocks 71, 711 and 81, 811 are similarly constrained by rollers 17, 18 engaging in arcuate grooves 19, 20. Movement of blocks 5, 6 towards or away from each other, to alter the beam width, is controlled by roller-driven belts 31, 32. Arms 37, 38 are rigidly attached to the upper parts of the belts, and engage in the slots of slotted members 39, 40 attached to block 5. Similarly arms 41, 42 are rigidly attached to the lower parts of the belts, and engage in the slots of members 43, 44 attached to block 6. Thus movement of the belts, caused by turning handwheel 36, moves members 39, 43 and 40, 44 towards or away from each other, according to the direction of turning, with corresponding movement of blocks 5, 6. Handwheel 45 operates a similar arrangement for controlling the movement of the other pairs of blocks. In the modification of Fig. 5 (not shown), movement of the blocks is controlled by an arrangement of screwed rods instead of belts.

Title: A process for the preparation of mono-cyclic ketones with more than nine ring members
IPC: C07C49/413
Filed: 1925-05-18
Abstract: Carbocyclic ketones having more than nine ring members are prepared by treating dicarboxylic acids having more than ten carbon atoms, or their salts or alkyl derivatives, by ketone preparation methods, preferably by employing the thorium or cerium salts.  In one method, the thorium salt of the dicarboxylic acid, e.g. tetradecane-1 : 14-dicarboxylic acid, is heated to 300 DEG -400 DEG  C., preferably in a vacuum, and the cyclic ketone, e.g. cyclopentadecanone, is obtained from the distillate by repeatedly fractionally distilling or by forming the semicarbazone.  The preparation of the cyclic ketones from cycloundecanone to cyclopentadecanone and cycloheptadecanone by this method, starting with the corresponding acid, is described. Cyclopentadecanone may also be obtained by starting with the cerium salt or by heating tetradecane-1 : 14-dicarboxylic acid in the presence of thorium oxide.  The cyclic ketones obtained have a characteristic smell, that of cyclopentadecanone and the adjacent ketones resembling musk and civet in place of which they can be used. The cyclic ketones on oxidation with chromic acid give each a dicarboxylic acid, e.g. cycloundecanone gives nonane-1 : 8-dicarboxylic acid.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the preparation of cyclodecanone, cyclohexadecanone, and cyclooctadecanone from the thorium salts of the corresponding dicarboxylic acids; the addition of a good conductor of heat, such as copper or iron turnings, and heating to above 400 DEG  C. in the preparation of the cycloketones from the thorium salts, and their isolation by fractionally distilling and then forming the semicarbazone; the recovery from the mother liquid of the semicarbazones of a mixture of semicarbazones from which a mixture of ketones, mostly isomeric with the cycloketones, can be obtained; the preparation of cyclopentadecanone by heating tetradecane-1 : 14-dicarboxylic acid alone or in the presence of cerium or of acetic anhydride, or by gradually heating its anhydride alone or in the presence of thorium oxide, the temperature being raised to over 400 DEG  C. and a vacuum being preferably employed towards the end, or from a mixture of the thorium and cerium salts of the acid; and the preparation of mixtures of the cycloketones starting with mixtures of the thorium salts of the corresponding dicarboxylic acids.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1439713 Correlation system THOMSON-CSF 25 March 1974 [27 March 1973] 13136/74 Heading G1U [Also in Division H4] A signal X(t) which is zero outside an interval -a#t<a and which when correlated with a single copy of itself centred at a time #=# 1  produces a correlation function shown in Fig. 1A, is correlated with a signal Y(t) consisting of an appropriately scaled sum of a plurality of non-overlapping copies of itself centred at different times, i.e. for two copies where # 1 >2a and # 2 ># 1 +2a, to give a correlation function as shown in Fig. 1C. Since the copies of the signal X(t) that constitute the signal Y(t) are non-overlapping, the correlation function B(#) can be evaluated for a specific value of # by a single correlation circuit comprising a multiplier feeding an integrator, merely by applying the signal X(t-#) to one input of the multiplier, and the signal Y(t) to the other, the signal Y(t) being constituted by the repetition of the signal X(t) with the appropriate delays of # 1  and # 2 . As applied to a radar system, Fig. 3, an echo signal from a receiver 12 is applied to one input of a multiplier 2, and the original transmitted signal is applied successively via delays 17 & 18 to the other input. The output of the multiplier is integrated 3 and applied to a threshold circuit 15 to indicate whether or not the echo lies within the range # m  to # M2 , Fig. 1C.
